In a cathode-ray tube, a beam of electrons (the cathode ray) is deflected in a region of electric field on its way to a fluorescent screen, as shown in the figure. Consider the parallel-plate arrangement in the figure, and assume that the electric field E = 400 N/C is uniform between the plates and that E = 0outside the plates. The beam of electrons is injected horizontally with velocity v0 = 5.0 × 106 m/s. If the width of the...

A cathode ray tube (CRT) is used to display images in some televisions and computer monitors by accelerating electrons from the cathode toward the anode, which is at a higher potential than the cathode. If the potential difference between the cathode and anode is 25 kV, at what speed do the electrons move as they reach the anode? Express your answer in scientific notation. (in m/s) (Hint: energy is conserved)

Older televisions display a picture using a device called a cathode ray tube, where electrons are emitted at high speed and collide with a phosphorescent surface, causing light to be emitted. The paths of the electrons are altered by magnetic fields. Consider one such electron that is emitted with an initial velocity of 1.85 107 m/s in the horizontal direction when magnetic forces deflect the electron with a vertically upward acceleration of 5.45 1015 m/s2. The phosphorescent screen is a...

Cathode ray tubes (CRTs) used in old-style televisions have been replaced by modern LCD and LED screens. Part of the CRT included a set of accelerating plates separated by a distance of about 1.52 cm. If the potential difference across the plates was 26.5 kV, find the magnitude of the electric field (in V/m) in the region between the plates. _________V/m

Older televisions display a picture using a device called a cathode ray tube, where electrons are emitted at high speed and collide with a phosphorescent surface, causing light to be emitted. The paths of the electrons are altered by magnetic fields. Consider one such electron that is emitted with an initial velocity of 2.05 x 10^7 m/s in the horizontal direction when magnetic forces deflect the electron with a vertically upward acceleration of 5.30 x 10^15 m/s2. The phosphorescent screen...

An x-ray tube houses a filament and a target material that act as a cathode and anode. The cathode and anode are separated by a distance of 3 cm with a potential difference of 86 kV that establishes a uniform electric field. Determine the magnitude of the force an electron would experience if located between the target material and the filament. F = _____ N

An X-ray tube houses a filament and a target material that act as a cathode and anode. The cathode and anode are separated by a distance of 2 cm with a potential difference of 91 kV that establishes a uniform electric field. Determine the magnitude of the force an electron would experience if located between the target material and the filament. F = N

4. Before television screens were all flat, they used to work by boiling off electrons ("cathode rays") from plates a hot filament and accelerating them towards a phosphor-coated screen. The acceleration was performed with a pair of charged parallel plates, as in a capacitor, with small holes to allow the beam to pass through. The beam was steered horizontally and vertically across the screen by varying the magnetic fields in deflecting coils. By varying these deflecting fields, the beam was...
